DESCRIPTION

 

Allow Web traffic for trusted

When this box is selected, the ZyWALL blocks Web access to sites that

 

web sites only

are not on the Trusted Web Sites list. If they are chosen carefully, this

 

 

is the most effective way to block objectionable material.

 

 

 

 

Restricted Web Features

Select the check box(es) to restrict a feature. When you download a

 

 

page containing a restricted feature, that part of the web page will

 

 

appear blank or grayed out.

 

 

 

 

Block

ActiveX is a tool for building dynamic and active web pages and

 

ActiveX

distributed object applications. When you visit an ActiveX web site,

 

 

ActiveX controls are downloaded to your browser, where they remain in

 

 

case you visit the site again.

 

 

 

 

Java

Java is a programming language and development environment for

 

 

building downloadable Web components or Internet and intranet

 

 

business applications of all kinds.

 

 

 

 

Cookies

Cookies are files stored on a computer’s hard drive. Some web servers

 

 

use them to track usage and provide service based on ID.

 

 

 

 

Web Proxy

A server that acts as an intermediary between a user and the Internet to

 

 

provide security, administrative control, and caching service. When a

 

 

proxy server is located on the WAN it is possible for LAN users to

 

 

circumvent content filtering by pointing to this proxy server.

 

 

 

 

Allow Java/ActiveX/Cookies/

When this box is selected, the ZyWALL will permit Java, ActiveX and

 

Web proxy to trusted web

Cookies from sites on the Trusted Web Sites list to the LAN. In certain

that are known and trusted.
